Unreleased ABBA demos to be performed

To add just a bit more to what wombat already said (he knows about this stuff more than I do): there's no 'lose' of sound with digital, since, at least theoretically, a regular CD (44.1/16) covers the whole range of frequencies that humans can possibly hear (and so in my opinion HD audio is simply an overkill), and it objectively has MUCH more dynamical range than any vinyl (this is especially noticeable with recordings of orchestral music). What does make the difference to the quality of sound is the analogue to digital converter that one uses (either in the process of recording, or remastering an album from tape). As wombat already explained, in the early days of digital, the digital converters used to be pretty crude compared to what you have today, so many of the early cd's sounded bad for this reason, though there are many exceptions. Many of the early digital remasters from the 80's still actually sound really good even in comparison to more recent remasters (as many audiophiles will tell you).

Think about digital photography, it's the same principle. A high end camera is going to produce much better results than a cheap camera on a smartphone, even if you have the same number of pixels in both cases. It's all comes down to the quality of your equipment rather than the type of medium which you are using (maybe vinyl or tape does inherently produce better sound than digital, but if there are such differences they are rather subtle - in my judgement, a well recorded digital audio can sound as 'warm' or natural as any analogue recording, hence in my opinion, the recording and mastering process is way more important than the physical medium that one uses).

That does, however, lead to a slightly different sound, does it? If they did that to ABBA's back catalogue (which B&B surely wouldn't allow), the result would sound slightly different from what we know, especially considering that ABBA had so many things hidden in their mixes that probably hardly anyone would remember whether certain things from the multitrack are actually ver low in the mix or not present at all.

He'd need to proper motivation for that.

Roughly speaking, as Paul Stanley once said, and I have no reason to argue - "it takes three times longer to mix than it does record".

Benny might get Ludwig to do it.... Benny wouldnt have time.

what would be MORE fun, would be a software delivery package where you get a set of Abba songs with all, or most, of the original multi-tracks.. and then you can create your own customized mix.

I know, never happen.....

Nobody in their right mind would do that. Thats a bands private intellectual property and they'd be crazy to release that. Can you imagine the horrible re-mixes of their glorious songs suddenly unleashed upon youtube? LOL

I've seen a few multi-tracks bootlegged from files cracked open via the Guitar Hero game. Bands were paid big bucks to provide original multi-tracks to the game company for said purpose and it didnt take long for somebody to crack that wide open. Some of these werent the original bands files, they were made for the game, but some were from the bands.

But thats it, thats all I've ever seen, at least available on bootleg.
